he's only 9 months old!!!! A few weeks back he figured out how to climb/hop the baby gate to get out of the kitchen. He's eaten about 4 hardback books, torn up all the stuff off my coffee table. I've sprayed as much as I can with the bitter apple but he's just destroying everything. I'm afraid to get a Christmas tree this year!!

I'm worried about putting him a crate because I live in apartments and I think he'll bark all day.
Help... Calgon.... take me away!!!
